Question 7.4

How to tell Gnus not to try to send mails / postings while I’m offline?

Answer

All you’ve got to do is to tell Gnus when you are online (plugged) and when you are offline (unplugged), the rest works automatically. You can toggle plugged/unplugged state by saying J j in group buffer. To start Gnus unplugged say M-x gnus-unplugged instead of M-x gnus. Note that for this to work, the agent must be active.
